For me, HDA was worked correctly on all devices I've tried it on, with minimum fuss or issues. The only issues I've ever had have been where the BIOS does not correctly indicate what the sources/sinks are, and a little bit of tweaking is required, eg to have front audio muting speakers when connected. This does require some tweaks, and the whole cad/nid syntax is slightly confusing - I got mine right by voodoo, I think. If there are budding technical writers out there who do understand this, and fancy contributing, I think that would be fantastic. Cheers Tom
